New Product Launch | AP010S New Turning Grade & SC1 New Chip Breaker for Superalloy Machining
In the field of difficult-to-machine materials, common products on the market often suffer from short service life, low machining efficiency, severe built-up edge formation and unsatisfactory workpiece surface quality. To address these issues, ACHTECK Tools launches the AP010S, a new PVD turning grade for superalloys, paired with the new SC1 chip breaker.
PART 01 AP010S: New Turning Grade for Superalloys
The AP010S grade is mainly designed for machining difficult-to-machine materials such as nickel-based, titanium-based and iron-based superalloys, as well as stainless steels. Compared with conventional grades, it delivers significantly improved performance, markedly extended tool life and effectively enhanced machined surface quality.
Grade Features
◾ Newly developed ultrafine-grained tungsten carbide, with substrate strengthening technology applied to enhance the bonding strength between cobalt and tungsten carbide and improve the high-temperature resistance of the binder phase.
◾ Adopts special coating post-treatment technology to improve the coating's resistance to built-up edge (BUE) formation and high-temperature oxidation.
◾ Brand-new nano-grained high-aluminum coating with exceptional hardness, structural and chemical stability, perfectly suited for high-speed machining of superalloys.

PART 02 SC1: New Chip Breaker for Superalloys
🔺Key Chip Breaker Design Features 🔺Chip Breaker Comparison
Developed for the finishing requirements of stainless steel and superalloys, the newly launched dedicated SC1 chip breaker delivers excellent chip breaking control. It achieves stable chip breaking performance under low feed rate and small depth of cut conditions. Its curved cutting edge design reduces cutting force, minimizes burr formation and flank wear. When paired with the newly developed AP010S — the dedicated grade for difficult-to-machine materials — it further optimizes machined surface quality, ensures stable machining processes and extends tool service life.
